1864 EXTENSION: further 3-bays to Dunlop Street (remnant of warehouse), slightly advanced. Detailed as above, but with giant pilastrade between 1st and 2nd floors, with anthemion necking (no applied columns), and Greek-key chip-carving in frieze to 2nd floor (no balcony). 3rd floor windows narrower than those above and with broad, chip-carved pilasters dividing and paired capitals to each. Casement windows to 2nd and 3rd floors and top hoppers at 1st floor.

Notes

Built on site of former Buck's Head Hotel. Forms a watershed in structural logic, iron-framed (McConnell's patent) and disguised yet with applied IRON columns. Thomson's warehouse designs made reference to those of David Hamilton. Similar ornament was employed earlier by Thomson at Grosvenor Building (1859) and the Cairney Buildings (1860), and later at the Grecian Building (1865) and the Egyptian Halls (1871-3), Glasgow. The modern extension to S in Dunlop Street has followed the 1864 design in a more severe and lower key.

Buildings are assigned to one of three categories according to their relative importance. All listed buildings receive equal legal protection, and protection applies equally to the interior and exterior of all listed buildings regardless of category.

ACategory A

Buildings of national or international importance, either architectural or historic, or fine little-altered examples of some particular period, style or building type. (Approximately 8% of the total).

BCategory B

Buildings of regional or more than local importance, or major examples of some particular period, style or building type which may have been altered. (Approximately 51% of the total).

C(S)Category C(S)

Buildings of local importance, lesser examples of any period, style, or building type, as originally constructed or moderately altered; and simple traditional buildings which group well with others in categories A and B. (Approximately 41% of the total).
